I agree with Otto and Sunil, but it is always easier to spend somebody else's money. As far as your quote goes, it seems a little high to me. Usually a bid is roughly half labor and half materials, and I know a contractor won't be paying laborers over $3000 for work that shouldn't take more than a week. Lumber prices have shot up around here lately, but I still think a price closer to $4000 or $5000 including labor would be more likely.
